both sides whether or not we should attack or not? why not seek congressional authorization? wouldn't that give him some cover, if congress said we're not authorizing, he could say to the american public, well, i tried? >> he absolutely need some cover, especially what you saw last night in parliament, apparently during that telephone call, with lawmakers, with secretary kerry they learned parliament had rejected david cameron's call for taking action in syria. the u.n. is not on board. you know, former president carter, we just reported, that former president carter said a unilateral u.s. attack would be illegal. so i mean, the president needs some friend here, and one way to do that would be to bring a lot of members ever congress in, consult with them, then seek an actual authorization for some specific thing to be done in syria. alisyn: we will see what happens this weekend as things are heating up. byron york, thanks for your analysis. >> thank you, alisyn. alisyn: true.
